I've built my personal site on XSLT a couple times just to see how far I could push it.
It works surprisingly well, the only issue I ever ran into was a decades old bug in Firefox that doesn't support rendering HTML content directly from the XML document. I.e. If the blog post content is HTML via cdata, I needed a quick script to force Firefox to render that text to innerHTML rather than rendering the raw cdata text.

with xslt it probably could be.
